Abstract

PROBLEM TO BE SOLVED: To provide a binding implement capable of firmly binding documents regardless of their piled-up thickness though it is simple in structure, and low in cost while being easily disposed of, and also provided a binding machine capable of punching the documents and simultaneously mounting the binding implement to the documents. SOLUTION: This binding machine is provided with a punching blade 1 capable of punching documents and simultaneously mounting a binding implement to the documents by punching the documents in a state that the binding implement is charged wherein the binding implement formed out of planes in a U shape in cross section, has a projection at its top part, and also has both the sides of it formed in a saw blade shape each.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding device for binding a document or the like and a binding machine for inserting the same into a document.

[0002]

2. Description of the Related Art A conventional document binding device is made of a hard material such as a metal, and is inserted into a document that has been perforated in advance and mounted.

[0003]

This has the following disadvantages. The structure of the binding device is complicated, it takes time to manufacture, and the price is expensive. It was also difficult to remove the bindings when disposing or shredding them, and to dispose of the bindings themselves. Not suitable for small number of documents,
This required the use of a completely different binding method, stapler, or the like. In order to attach the binding device, a two-stage operation of punching a document and attaching the binding device was required. Also, it took time to attach the binding device itself. When punching documents,
This disposal was necessary because the perforated part was discharged as paper waste.

[0004]

Means for Solving the Problems The following problems are solved by the following constitution. (B) To provide a binding device that has a simple structure, is inexpensive, and is easy to dispose at the time of disposal, and that can be strongly bound regardless of the thickness of a document. The binding device 2 has a shape constituted by a flat surface, and can be made of a material other than metal, such as paper or a soft plastic plate, which is inexpensive, easy to manufacture, and easy to dispose. The binding device 2 has a shape having an overhanging upper portion and saw-toothed sides, and the thickness of the document is reduced by holding down the document by overhanging and hooking a perforated portion of the document at both sides of the sawtooth shape. Regardless, it allows you to bind documents. In addition, insert the tip of the binding tool after attachment to the document, so that it can be more firmly fixed,
A slit is provided in the overhang. (B) To provide a binding machine capable of perforating a document and simultaneously attaching a binding device to the document in a single procedure. The perforation blade 1 has a U-shaped cross-section with both sides curved, and the binding tool 2 is loaded in close contact with it. The punching blade 1 further has a groove near the distal end thereof for inserting the distal end of the binding tool 2, so that the binding tool 2 can be inserted into a document and punched in a state in which the binding tool 2 is closely attached to the punching blade 1. It has become. The punching blade 1 gives a U-shaped punching shape to a document to be punched due to its cross-sectional shape. As a result, the document can be reliably perforated by giving a downward clearance at the time of perforation without cutting out a part of the document and discharging paper waste. In addition, the U-shaped perforated shape is such that the binding device 2 attempts to return to a planar shape due to its elasticity after being inserted, so that both the saw-toothed sides of the binding device 2 and the curved portion of the perforated portion of the document are caught. The document can be bound. As described above, it is possible to simultaneously perform the punching of the document and the attachment of the binding device to the document.

[0005]

Embodiments of the present invention will be described below. The binding machine includes a punching blade 1, a punching blade guide 3, a punching blade guide support 4, a base 5, a binding device storage case 6, a binding device loading spring 7, a punching handle 8, a pedestal 9, and a punching handle return spring 10. You. The perforating blade 1 is connected to the perforating handle 8 by a connecting pin on an upper portion thereof. When the perforating handle 8 is pressed, the perforating blade 1 descends along the perforating blade guide 3 with the binding tool 2 loaded, and perforates a document. The binding device 2 is inserted together with the perforation blade 1 into the document to be perforated, and when the overhang reaches the upper surface of the document, the binding device 2 cannot further descend, while the perforation blade 1 further descends, so that the leading end is It comes off the groove of the drilling blade 1. The binding tool 2 that has been in close contact with the curved punching blade 1 separates from the punching blade 1 by trying to return to the original planar shape with its own elasticity, and at the same time, comes into stronger contact with the document on the opposite side. Even when the perforation is completed and the perforation blade 1 rises due to the repulsive force of the perforation handle return spring, the binding tool 2 remains intact due to friction between itself and the document (the surface in contact with the document and both sides of the saw blade). Stop at the position. Then, the saw blade-shaped both sides of the binding tool 2 to be restored to the planar shape are the punching blades 1.
As the document is pulled out, the curved portion of the U-shaped perforated portion of the document is caught and the document is bound. In the process, the next staple 2 stored in the staple storage case 6 is pushed out by the staple loading spring 7 so that the leading end of the piercing blade 1 returns to the original position. Is loaded by entering. The binding device 2 that binds the document can further firmly fix the document by folding the leading end of the binding device 2 above the document and inserting it into the overhanging slit.

[0006]

According to the present invention, a material other than metal, such as paper and a soft plastic plate, can be used for the binding device due to its planar and simple structure, so that it is inexpensive, easy to manufacture, and easy to dispose. The structure of the binding device enables a strong binding method regardless of the thickness of the document. With a single operation, it is possible to simultaneously perform punching of a document and attachment of a binding device to the document.
Ejection of paper waste from documents due to perforation can be eliminated.
